timendus / ticalc.link

A website that can send files to your calculator through WebUSB and ticalc-usb

ticalc.link

This is a website that allows the user to upload files to their calculators using WebUSB. No complicated installation instructions, just open the website, follow the three on-screen steps and you're done.

Status of this website

This website is currently very experimental. I have successfully communicated with my TI-84 Plus with it, and sent files to it. However, it comes with absolutely no guarantees that it can handle other models or even other version of the TI-84 Plus, nor that it can properly parse and send any file you throw at it. So be warned.

If you run into issues, please report them or submit a PR at the ticalc-usb library.

Most of the time, it won't send the files to the calculator??

TI-84+ CE support?

Any chance of supporting the TI-84+ CE?

add support for B84 files

"The file you have selected does not seem to be a valid calculator file"

Hello,

I am encountering an issue when uploading a file to my calculator.
I built a file using the toolchain, but when i attempt to send it, it doesn't let me.

How can i fix this or is it a bug?

it doesent support ti 83 plus and the 8xv files dont work

it doesent support ti 83 plus and the 8xv files dont work

Having trouble with the send button

It will not send, it connects the calculator, selects the file, and then when I click send it unconnects the calculator and wont let me reconnect it until i reload and unplug the cord/website

Programs always have error on TI-84 CE

Hello,

I am able to upload programs but my inability to play them is a bit saddening. I can upload perfect, but i can't do anything with them except getting errors. Please fix this if you can, but i know you have a very limited time

Best Regards,
Squeezy

Google analytics.

Would it be possible to replace Google Analytics with something more privacy respecting like Plausible Analytics?

I would prefer to not have google tracking me while visiting your site.

connectio issue?

SO, I've got my TI-84 Plus CE plugged in correctly, but the site doesn't recognize it. Any suggestions?

Interesting ChromeOS Issue

I can transfer files to a TI-84 Plus CE and python edition, but when I tried this with a regular TI-84, I was only able to transfer a broken 2048 file, which ended up launching, but didn't really work. After that, nothing happened when I clicked the send button.

Cannot send.

I can select a calculator and file. But nothing I do will start the process to send file over. I am using a TI-84 Plus.

Unnable to select calculator (ChromeOS)

I've tried, and this is what happens

Some files not sending properly for the TI-84+ CE(-T Python Edition)

There are some files that are being sended properly.
I've made a list of files that do work and files that do not work.
I think that the problem has something to do with the file size.
The files that are being sent are all small...

files that work:

• BATTERY (https://www.ticalc.org/archives/files/fileinfo/475/47544.html) [Only after replugging the cable, if tried another file first]
• θLIGHT (Within the CLOCKCE zip) [DOES send, but NOT correctly. the theta is changed into another symbol]
• θDARK (Within the CLOCKCE zip) [DOES send, but NOT correctly. the theta is changed into another symbol]

files that don't work:

• BOARDCE (https://www.ticalc.org/archives/files/fileinfo/475/47549.html) [does send sometimes, but then just as empty program]
• CLOCKCE (https://www.ticalc.org/archives/files/fileinfo/475/47562.html) [does send sometimes, but then just as empty program]
• STORYCE (https://www.ticalc.org/archives/files/fileinfo/475/47553.html) [[does send sometimes, but then just as empty program]
• RNDMNMBR (https://www.ticalc.org/archives/files/fileinfo/475/47535.html) [gives also an error to the user]

Won't let me 8XK Files

I've tried sending all kinds of different 8XK files, like Doors CS7, or ION, but they all say "The file you have selected does not seem to be a valid calculator file".

Not all file types can be sent

The issue

People report all kinds of issues with not being able to send certain kinds of files. The reported problems seem to fall into three categories:

1. The file picker does not allow the user to select the file, because there's a check on file extension (currently limited to .8xp,.8xg,.8xv,.83p,.83g,.82p,.82g)
2. ticalc.link does not allow sending the file, with the message "The file you have selected does not seem to be a valid calculator file" (tifiles.isValid(file) returns false)
3. The file seems to send, but gives an error or doesn't show up on the device

Category 1 and 2 exist to prevent category 3. So the ones in category 3 are bugs, the ones in category 1 and 2 are technically "by design" because the library doesn't support each and every file. But I understand that both are pretty annoying.

Please note that Texas Instruments' file types are not really documented anywhere, so much of this is a dark art. The current file parser code is largely a port of tilibs (https://github.com/debrouxl/tilibs). Fixing exotic parsing issues or adding new file types is therefore not as easy as I'd want it to be.

This issue is here to at least document the different types of problems, collect ideas to solve them and maybe inspire someone (or myself) to fix them 😉

Thank you all for sending these in!

Solution to category 1 problems

Some file extensions are supported by the parser, but not allowed by the file picker. These can easily be fixed. I do however feel like we need to test each type before we allow them. If you can run ticalc.link locally, you can easily change the list of allowed file types here, and test to see if the file then sends correctly:

ticalc.link/src/index.js

Line 103 in eb56999

input.accept = '.8xp,.8xg,.8xv,.83p,.83g,.82p,.82g';

I suspect we can probably parse these files (but need to test):

• .8xs
• .8ca

Other file extensions are not supported by the file parser, so those are basically category 2 problems that are caught in an earlier stage. For those we need additional work on the file parsing (see below).

I suspect these files can't currently be parsed:

• .8ek
• .b84
• .8xk

Solution to category 2 problems

Here's the check that says files are valid or not:

https://github.com/Timendus/ticalc-usb/blob/2a0f5e4bae433f5e411faacdd8d6c31d964fb864/src/tifiles.js#L36

If there are program (.8?p), group (.8?g) or variable (.8?v) files that ticalc-usb says are invalid, but are really valid files for supported calculators, then we probably have a bug in this or related code.

The code that parses files currently (probably) doesn't support files other than program, group or variable files. So the fix for being able to send other files is adding parsing support for additional file types. This would need to be written by someone, and I'm open to contributions 🙂

Solution to category 3 problems

These are almost always bugs. A file should not be loaded and parsed correctly, but not sent properly. I'm not entirely sure how people manage to end up in these states 😄 If people have example files or steps to reproduce the issue, please share them below.

One of these weird issues may be with sending .8xv files (#26). This could be a good place to start work on this category.

An error with index.js

I get an error in the console every time that I try to send a file, the file doesn't even arrive.
I'm using a TI-84+ CE.
The website and the calculator are reacting to each other though

No support for CE files other than 8xp or 8xv

Will this come at any point?

Can't install OS and apps bundle

When I try to select the TI84CEBundle-5.8.0.22.b84 file (downloaded from here), it says it's invalid. I know people usually only transfer 8x* files, but I have to reinstall my OS because my RAM was almost full. Using TI 84 Plus CE on Samsung Chromebook 3. I was able to transfer a couple programs, so it's not the computer's fault.

unable to select calculator after new chrome OS update

I recently got a TI-84 Plus CE, and as a chromebook user, I do not have many options to add files to my calculator. However, this website was great, and I have been using it for several days.
Unfortunately, after installing a new chrome OS update, I can no longer see my calculator in the "select calculator" stage. I have tried to see if it is an issue on my calculator; resetting RAM, checking for anything weird, etc. I have been using the same cable (I tried to use a different cable at one point to see if that was the issue), and my calculator OS shouldn't be too high of a version to make it harder to add files (OS version 5.4.0034). After updating, my chrome OS version is now version 114.0.5707.0 (Official Build) dev (32-bit).

Can't send .8xs files

^title^

It either does nothing when I press "send it" or it says "something went wrong."

.8xv files will not transfer to TI-84 Plus CE

Hey there,

I'm currently on Chrome OS (Version 94.0.4606.124) and when I try to send a .8xv file to ticalc.link, it says it has been successfully sent, yet I cannot find the file on my Calculator. Another issue I'd like to bring up is that when trying to open the file, I have to go to "All Files". This should show with the other selected files.

Thank you for your time and effort on this project.

Select Calculator not working

I am using Chrome Beta (Version 112.0.5615.49 (Official Build) beta (64-bit)) on Ubuntu 20.04.4 LTS, and I have a Ti-84 Plus CE. Chrome detects the calculator as a Serial Port, but for some reason, ticalc.link doesn't show that it's connected to a calculator, but Chrome says that it's paired. Here is me having the problem.

App files and update files not supported

I can’t download updates and new apps for my ti-84+se the file type is .8xk

Will say it's connected, but then won't connect to calculator

Unable to Connect to TI 84 Plus or CE

I have tried to connect to both of my models in the 84 family, but neither have shown in the list of devices to connect to. Anyone have any idea what is going on? I am on a Windows 10 PC running Chrome.
EDIT: I can however connect on Chromebook, but sending a C file sends it as an empty TI-BASIC file.

Issues with calculator selection

I have been using this website for sending files to my ti84 plus ce and it's worked great! Just recently though I would select my calculator and it would show up with the beta warning but when I click 'Okay' the page will crash with error code SIGILL.

Unable to Progress Past Step 1

OS: Windows 10 Home 20H2
Browser: Edge Version 89.0.774.76 (Official build) (64-bit)
Calculator: TI-84 Plus CE Revision M with OS 5.3.0

Issue: I cannot get the first step to be marked as completed. When I opened ticalc.link, the 'Select Calculator' was in blue. I clicked it, selected my calculator, and clicked 'Connect'. However, step 1 did not turn into a green check mark nor did I get any warning about the TI-84 Plus CE's support still being in beta. If I click on step 1 again, Edge will show that my calculator is currently paired.

Although step 2 was greyed out, I could still click on it and select a file. Step 2 would turn into a green check mark but step 1 would stay the same blue color.

Step 3 is greyed out and I cannot interact with it no matter what file I select (ASM or Basic) in step 2.

The only error in the console is

DOMException: Access denied.

Which takes me to this function. The error is the ".error(e)" on the last line. e is undefined.

suggestion: be able to send more than just the 8xp files

add support for the 68k calculators

i own a ti 92 plus and would find it very useful to be able to use my chromebook to get files on it.

wont send a file

the file here wont work for some reason it just disconnects the calculator

8xl files can't be sent :(

I used to use TI Connect CE, but when I found this, I started only using it because it was much easier and it was in HTML5, which meant I could use it on my school computer. Eventually my PC broke, and I was forced to use this site. It's wonderful, but surprising to me that after all this time TI 84 Plus CE is still in beta; I would imagine it's what the majority of ticalc.link users use it for. Over the past 4 months or so I've been really interested in Brainfuck and how it's so complicated to do simple things like the Fibonacci sequence. So I tried to install Brainfoo for the CE. But it has necessary 8xl files, which unfortunately cannot be sent on ticalc.link. I started work on my own brainfuck interpreter, but eventually dropped it, being much harder than I thought. I've came back to it a few times, but I doubt I'll ever finish it with the knowledge that a better one already exists, but I just can't install it. Eventually I decided to come here and make this issue to ask if support for CE files like .8xl will come any time soon. I hope I get a response :) I've checked and made sure this isn't a copy of another. At least, it's not mentioned in this issue.

TL;DR, I'd love to know when (or if) support for more obscure CE file extensions will come, as they're sometimes (albeit rarely) necessary.

Can't send .8ek, .8ca, or .b84 files

My calc: TI-84+ CE Python (H/W revision S)
OS version: 5.7.0

.8ek files are TI-84+CE applications, .8ca files are pictures for the CE, and .b84 files are bundles (basically a fancy .zip). I'm unable to move these to my calculator using ticalc.link. It just says that it isn't a valid calculator file. Could you please add support for these?

"Expected virtual packet type 47872, but got 8 instead" when using TI-84+CE

I'm getting the following error when trying to send a program to my TI-84+CE:

Uncaught (in promise) Expected virtual packet type 47872, but got 8 instead
(anonymous) @ index.js:formatted:207
async function (async)
(anonymous) @ index.js:formatted:195
(anonymous) @ index.js:formatted:207

Here's the relevant packet capture.

Send button not working

can't multi select files

in chrome os, you can multi-select files so it takes forever to put some programs on to the calculator

84PSE gets stuck during file transfer

On Windows using Chrome, I'm able to connect to my 84+SE with OS 2.55MP, but something seems to get stuck during the transfer such that I need to unplug USB from the calculator for it to come back and the file doesn't actually end up on the calculator.

It looks like the last chunk of data is expected to elicit a response from the calculator, but the calculator still seems to be waiting for something so the transfer gets wedged.

Can't send 8xk files and can't send multiple files at once

Can't Connect to a Renamed Calculator. Add Manual Override?

ticalc.link appears to determine what calculator is connected by checking its name. Unfortunately, this means that people such as reesericci and I cannot use our TI-84 Plus CE calculators with ticalc.link because we've renamed them to something other than the default 'TI-84 Plus CE' using CERMASTR.

Is there another way to identify what calculator is connected such as the OS version? Could there be an 'advanced' tab that lets the user manually select what calculator they are using?

no suport for 8ck files or for the ti 83
